Cracking Android pattern lock in five attempts

The researchers say cracking the code could be achieved by sneakily filming a victim whilst using their device in public.

This footage would then be fed into the algorithm, which then gets to works on guessing the lock pattern within seconds.

The attackers would not even need to be close to the victim, as the team was able to steal information from up to two and a half metres away by filming on a standard smartphone camera, and from nine metres using a more advanced digital SLR camera.
